Investigation of the Feasibility of the Electron Beam-Excited, High- Pressure Recombination Laser

Abstract

The objective of the research described in this report is to determine the feasibility of developing a recombining electron beam-excited plasma into a pulsed laser of exceptionally high peak power. Currently accepted theory indicates that this should be possible. An electron beam-excited helium afterglow system, operating routinely at 5 atmospheres and capable of modification to 20, was developed and instrumented so that spectroscopic observation of transient emissions in the visible and near IR region could be made with 10 nanosecond resolution. Construction details and system performance are presented.
